ABSTRACT:
A method for producing a lithium tantalate single crystal comprises the steps of preparing a melt consisting essentially of lithium tantalate in a platinum-rhodium crucible including 20 to 40 weight percent of rhodium, and growing a lithium tantalate single crystal from the melt in an oxidizing atmosphere, for example, in the atmosphere.
